The Flexofold™ Magnesium Anode (CMPNFXM) is a high-quality sacrificial anode specifically designed for use with Flexofold™ propeller systems. Optimized for freshwater environments, this magnesium version provides the necessary electrochemical protection to prevent galvanic corrosion on the propeller hub and blades where aluminum or zinc would be less effective. It features an outer diameter of 67mm (2.6") and a height of 38mm (1.5"), weighing in at a lightweight 0.260 lbs (0.118 kg). By acting as a shield for your high-end folding propeller, it ensures smooth operation and extends the lifespan of your vessel's underwater gear.
